012-05760B Free Fall Adapter
If your graphs were linear, measure the slope of each graph. Using your measured slopes
and the equation shown in the introduction to this experiment, determine the acceleration
caused by gravity. Be sure to include the units. Was the acceleration the same for each
ball?
Conclusion
Describe your laboratory experiment and discuss your results. Consider the following
questions: (1) Is the acceleration caused by gravity constant? (2) Is the acceleration
caused by gravity the same for all objects? Discuss the conditions under which you be-
lieve your results to be true. Include a discussion of the errors in your measurements and
how they affect your conclusions. How linear was your graph? How might you alter
your technique, or the experiment, in order to reduce experimental errors?
Suggested Additional Experiments
The Free Fall Apparatus can bring high resolution
timing to a variety of mechanics experiments. Any
conductive object can be timed as long as it can be
clamped in the release mechanism and is heavy enough
to depress the receptor plate when it strikes. The
Atwood’s Machine
Investigate F=ma
using a highly
accurate Atwood’s
Machine. Compare the velocities of a solid disk and a
ring as they roll down an inclined plane.

A short screw through
the hole in the release
plate will help hold the
cylinder in the release
mechanism.
Determine the acceleration of a cart pulled by
a constant force on a flat or inclined surface.
